Patented- Jani. '6, 1931 JOSEPH E. LARSON, or CLARKSQ NEBRASKA I sTooK snraRiiron Application filed July-'9,

The invention relates to improvements in' barriers for permittingsmall pigs or other is its principal application, itis to be understood that it is notrestricted to tlnsp'articu 10 lar field of use.

an efiicient and reliable construction which will permit small stock to readily pass, will not permit large stock to pass, and will readily' allow the large stock to withdraw from the barrier should they wedge their heads into the spaces through which the small stock passes.

WVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed description being accomplished by reference to the'accompanying drawings. I Fig. 1 is a side elevation of a hog feeder embodying the invention. V g

Fig. 2 is a'horizontal sectional view on line 2-2 of Fig. 1.

Fig. 3 is a transverse sectional view on line 3 3 of Fig. 1.

Fig.4 is a horizontal sectional view on the correspondingly numberedline of Fig. 3.

In the drawings above briefly described, 5 denotes a feeding house whose general con struction may be as desired. lVithin this house, I have shown a feed trough 6 and a hopper 7 for supplying feed thereto, a door 8 being provided in the roof of the house, through which to fill the hopper. Each of the side walls 9 of the house 5 constitutes one of the improved barriers and as they are both of the same construction, only one will be de-c scribed. i

The wall 9 is formed with a suitable number of rectangular door openings 10andwith flat vertically disposed wall portions 11 at opposite sides of said openings. A door 12 is provided. for each opening 10 and is of considerably less width than said opening.

These doors are hinged. at 13 to the Wall poe It is the object of theinvention to provide an exceptionally slmple; and'inexpens ve. yet

Flat barriers 15 he against thewall portions 11 at said other sides of the openings 10 and are adjustable tewardandfrom the free ed es 14%. of the doorsl2, to vary the width of the spaces 16 betweensaid barriers and door edges, to allow only stockunder predetermined size to pass. The upper and lower ends of the barriers. 15 are formed with horizontal slots 17 registeringwith bolt holes 18 (Fig. fl) I in the wall portions 11, and clamping bolts 19 are passed through these slots and openings for'tightly clamping the carriers 15 against the wall portions 1l to secure the former in adjusted position.

Due to the provision of an appropriate stop such as a sillstrip 20, the doors 12 can-.

not be swung inwardlinfand these doors are yieldably held in their closed positio-nsfby coiled springsQl connected thereto, the'inner ends of these springs being anchored to the hopper 7, 1n the present disclosure,

The construction described, allows the small'plgs to pass but prevents the larger" However, in case the ones from doing so. large stock should wedge their heads through the openings 16 and then find they can'get no further, they may readily withdraw. as

the springs 221 permit outward swinging of thedoors 12 for this purpose. These swing doors also come into play in case the small stock crowd each other when leaving the house 5., more than one attempting to pass through an opening 16 at the same time.

It willbe seen from the foregoing that while the invention is exceptionally simple and inexpensive and may be constructed with easeyit willbe efficient and generally advantageous. The details disclosed are therefore preferably followed. but within the scope of the invention as claimed, variations may be made. I
